THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 679,461, dated July 30,1901.

Application filed May 6, 1901- Serial NO- 58,922. (No model.)

To all whom, it may concern.-

Be it known that I, WILL J. KENNEDY, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Thill-Oouplings; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to thill-couplings.

The object of the invention is to provide a thill-coupling which shallbe simple of construction, durable in use, and comparatively inexpensiveof production and by means of which the shafts may be easily and quicklyattached to or removed from the axle and which when in operativeposition will be prevented from becoming accidentally disengaged.

With this and other objects in View the invention consists of certainnovel features of construction, combination, and arrangement of parts,which will be hereinafter more fully described, and particularly pointedout in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of myimproved thill-coupling, showing it in position for use. Fig. 2isalongitudinalverticalsectionalview. Fig. 3 is a detail perspectiveview of the thilliron rcmoved, and Fig. at is a similar view of thecoupling head.

The thill-coupling is composed of two parts, part 1 being thecoupling-head and part 2 be ing the thill-iron. The coupling-head isprovided with checks 3, having circular edges i and a segmental wall 5,formed with a T- shaped slot 6, the narrow portion of the slot being atthe rear, while the broad portion of the slot is at the base of thesegmental wall. The thill-iron is provided with a curved head 7,designed to fit between the cheek-pieces 3 and snugly fit the curvedwall 5 and is formed with a rearwardly-extending T-head 8, adapted toengage the T-slot 6 of the coupling-head and when in the position shownin Fig. 1 look the thill-iron to the coupling-head. Forward of the headis formed an enlargement 9, terminating on its lower side near its rearend in a lip 10, spaced from the head '7 and adapted to engage under theforward lower end of the segmental wall, while the laterally-extendingedges are adapted to engage the circular edge 4. of the lip. Thisshoulder has also an upper lip 11, which is adapted to engage the upperrear end of the segmental wall when the thilliron is raised to avertical or nearly vertical position. The ends of the head 7 are formedwith recesses 12, which are intersected by horizontal slots 13. Inassembling the parts these slots 13 receive short studs or lugs 14,projecting inwardly from the cheek-pieces 3.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of my invention will be readily understood without requiringa more extended explanation.

Various changes in the form, proportion, and details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a shill-coupling, the combination with a coupling-head providedwith cheek-pieces and an interposed segmental wall formed with a T-slot,of a thill-iron provided with a circular head to fit between saidcheek-pieces and provided with a T-head to engage said T-slot and withan enlargement formed with an underlyinglip spaced from the circularhead and designed to engage the lower side of the segmental wall,substantially as set forth.

2. In a'thill-coupling, the combination with a coupling-head providedwith cheek-pieces and a segmental wall formed with a T-slot, of athill-iron provided with a circular head to fit between saidcheek-pieces and segmental Wall and formed with a forwardly-projectingT-head to engage the T-slot,said cheek-pieces being provided on theirinner faces with studs and said curved head being provided at its endswith recesses intersected by horizontally-disposed slots, substantiallyas set forth.

3. In a thill-couplin g, the combination with a coupling-head providedwith cheek-pieces and an interposed segmental wall formed with a T-slot,of a thill-iron provided with a circular head to fit between saidcheek-pieces and provided with a T-head to engage said In testimonywhereof I have hereunto set my hand in presence of two subscribing wit-:0
